Mechanisms of neurologic disease can be cerebrovascular, neoplastic, movement disorders, infectious diseases. The causes of ischemic cerebrovascular disorders can be classified on the basis of the site of the source for the arterial blockage within the vascular system, from most proximal to distal.
